Title: System interconnection protective method and system for inverter
Inventor: OKATSUCHI CHIHIRO
IPC: H02M7/48
Filed: 1993-04-22
Abstract: PURPOSE:To allow positive stoppage of inverter by varying the current phase based on the frequency of output voltage from an inverter, variation ratio thereof, and the distortion voltage in the vicinity of zero-cross point upon disconnection of the inverter from an AC power supply system thereby varying the frequency to a predetermined value. CONSTITUTION:A zero-cross detector 28 detects zero-cross of AC voltage based on a voltage detected by a voltage detector 10. A distortion detector 27 then detects a distortion in the vicinity of zero-cross of AC voltage based on a detection value of the detector 28. When a distortion relay 32 detects that the detection value V27 of the distortion detector 27 is higher than a set value, an abnormality detection circuit 19 stops a drive section 15. Furthermore, a distortion variation detector 33 detects variation of distortion based on the detection value V27. A coefficient setting circuit 30 makes a decision whether the voltage has varied from the variation of output current from the inverter based on the ratio between an effective voltage value V and a current reference I* thus determining variables F1, F2 for varying the phase and amplitude of the current reference I*.

Title: Diversity receiver
Inventor: TAROUMARU MAKOTO
IPC: H04B7/08
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To prevent a diversity gain from being reduced even when slow fading takes place in spite of a simple configuration. SOLUTION: An antenna changeover device 3 properly selects an antenna 1 or 2 and a demodulated output is obtained from a reception section 4 that can detect a received signal strength indicator RSSI of a received signal. The antenna is switched when the RSSI is lower than a switching threshold value. Since a threshold value generating means 52 selects the switching threshold value within a range of an upper limit and a lower limit depending on a value resulting from filtering the RSSI by a low pass filter 51, fluctuation in the switching threshold value can be suppressed on the occurrence of slow fading.

Title: Optical integrated circuit
Inventor: MATSUDA KENICHI
IPC: H01L27/14
Filed: 1985-05-07
Abstract: PURPOSE:To prevent a crosstalk from generating due to a leakage light which passes through the passive layers in an optical integrated circuit by a method wherein the optical integrated circuit is constituted in a structure, wherein the regions other than the region where a signal light ought to b3e made to transmit in the passive layers are opaque for the signal light. CONSTITUTION:Active layers 12-14 consisting of AlGaAs and passive layers 15-17 consisting of GaAs are laminated on a GaAs substrate 11. These layers 15-17 are constituted of semiinsulative GaAs excluding light-transmitting regions 19a and 19b, while the regions 19a and 19b are constituted of semiinsulative AlGaAs. Moreover, light-receving elements 21a and 21b are formed in the layers 12-14. In this constitution, when a signal transmission is made from the layer 12 to the layer 14, for example, a signal light 28a to be outputted from a light-emitting element 20a passes through the region 19a and reaches the light-receiving element 21. At this time, signal lights to be outputted to the directions other than the region 19a and scattered signal lights do never reach the other light-receiving element 21b because the lights are absorbed in the GaAs regions in the layers 15 and 16.

Title: Write control system
Inventor: TANAKA KAZUO
IPC: G11B7/0045
Filed: 1983-06-03
Abstract: PURPOSE:To prevent double write without degrading a throughout by writing data if a write flag is not detected in the first rotation of an optical disc and performing the write of a pertinent flag and the read check of previously written data in the second rotation of the optical disc. CONSTITUTION:A read control circuit 23 sends an ID part of read data 33 to an ID register 25 and sends the write flag to a detecting circuit 24. The output of the detecting circuit 24 is checked if this ID part is an objective ID part; and if the output is ''1'', the write to a pertinent sector is not performed, and the control is transferred to the write to the next sector. Meanwhile, if the output of the detecting circuit 24 is ''0'', a write control circuit 22 is operated to send write data in a data buffer part 26 to an optical disc driving device (ODU). The ODU writes said data in a data part 3 of an optical disc (OD). After the processing of the last sector of write, an optical disc controller (OSC) performs read check RAW after write. RAW is performed as shown by Fig. (b), that is, a write flag 2 is written on the sector, where the write operation is executed, before the read check of the data part 3.
